UMBRELLA-RUNNER LOCK.

Specification of Letters Patent.

Application filed December 2, 1911.

Patented Mar. 11,1913. Serial No. 663,621.

To all whom it may concern:

Be it known that 1, CHARLES H. REID, a subject of the King of England,residing at Simcoe, in the Province of Ontario, Canada, have inventedcertain new and useful Improvements in Umbrella-Runner Locks; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The invention to be hereinafter described relates to umbrellas and moreparticularly to runner locks for the same.

In order to more clearly disclose the construction, operation, and useof the invention, reference should be had to the accompanying drawingsforming part of the present application.

Throughout the several figures of the drawings like reference charactersdesignate the same parts.

In the drawings: Figure 1 is a side ele vation of the device, inoperative position; Fig. 2 is a similar view, in inoperative position;Fig. 3 is an enlarged, longitudinal, sectional view, showing theoperation of the device; Fig. 4 is a top plan view of the ferrule,removed; Fig. 5 is an enlarged plan view of the means for changing thecombination; and Fig. 6 is a front view of one of the rings or disks,removed.

Referring to the drawings in detail, 1 in dicates an umbrella runner ofusual and well known construction. The lower section of this runner isformed as a ferrule 2 provided with a longitudinal slot 3 and aplurality of circumferential rings of ridges or parallel ribs 1, for apurpose to be later disclosed. About this ferrule portion are rotatablymounted a plurality of disks 5 each provided with an indexed flange 6and a radially extending slot 7. The disks 5 are so proportioned, ofcourse, as to just fill the space between the shoulders 8 at theopposite ends of the ferrule section of the runner.

Movably mounted within the hollow staff 9 of the umbrella handle is aspring actuated dog 10 provided with one tooth for each of the disks 5.The slot 3 of the ferrule section 2 receives the dog as the runner movestoward the handle of the umbrella. On the other hand, these teeth cannotpass freely through the disks 5 but are depressed by the edges of thedisks. However, as soon as the last disk has passed beyond itsparticular holding tooth, the dog will return to its operative positionwith each tooth projecting into the forward path of movement of thedisk. Thus, the disks and runner will be held in lowered position, orclosed.

In order to permit upward movement of the ferrule and runner to open theumbrella,

it is necessary, of course, to turn or move the disks 5 so that theirslots 7 will be alined with one another and with the teeth of the dog10, thus disengaging the disks from the dog. This is accomplished byusin a combination of the numbers or other inc ex characters on theflanges 6. In order to further facilitate the unlocking operation, clicksprings 11 secured to the inner walls of the flanges 6 and cooperatingwith the ribs or ridges of the circumferential rings 4, are provided.These springs also act in the nature of pawls to prevent reverserotation of the disks, thus rendering knowledge of the exact combinationnecessary to permit a successful unlocking operation of the disks.

In order to render the combination variable, the click spring of one ofthe disks may be adjustably connected to its flange 6 by means of abinding screw 12 playing in a circumferential slot 13.

The usual rib tip cup may be connected to the ferrule, if desired.

It is thought that the operation and use of the invention is clear fromthe preceding detailed description.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is:

1. In combination with an umbrella, a tubular umbrella staff providedwith a longitudinal slot, a runner slidably mounted thereon and formedwith a longitudinally slotted ferrule provided with circumferentiallydisposed ribs, a plurality of independently rotatable, slotted, andindexed disks mounted on said ferrule over the slot therein, a clickspring secured inside each of said disks and adapted to cooperate withsaid ribs, and a spring actuated dog mounted within said tubular staffand adapted to be projected through the slot therein and through theslots in said disks.

2. In combination with an umbrella, a tubular umbrella staff providedwith a longitudinal slot, a runner slidably mounted thereon and formedwith a longitudinally slotted ferrule provided with circumferentiallydisposed ribs, a plurality of independently rotatable, slotted, andindexed disks mounted on said ferrule over the slot therein, a clickspring secured inside each of said disks and adapted to cooperate withsaid ribs, means for adjusting one of said springs, and a dog mountedWithin said tubular stafi and adapted to be projected through the slottherein, and means for thus projecting said dog.

3. In combination with an umbrella staff, a runner movably mountedthereon and pro vided with a ferrule having a longitudinal slot, aspring-pressed pawl provided with a series of teeth adapted toprotrude'through 15 said slot, and a series of disks independentlyrotatable on said ferrule, each disk being provided with a slot which isadapted to receive one of said teeth, also with means for holding saiddisk in any position to which it may be turned substantially as setforth.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
